Grid connected hybrid power system design using HOMER

Abstract

This paper presents an economical expediency of grid connected hybrid (PV/Wind turbine) power system for rural area applications in the southern city of Bangladesh, Lobon Chora, Khulna. The analysis is carried out by investigating the potentials of wind and solar energy and collecting data from different sources. Hybrid Optimization Model for Electric Renewable (HOMER) software is used to analyze the available data and economic feasibility of the proposed hybrid power system. In this paper, two types of models named off-grid and on-grid are designed and optimized for comparison purposes. Also, a sensitivity analysis has been performed for each model in order to determine the effect of variations in grid energy cost on its total cost. The simulation results indicate that the proposed grid connected hybrid (PV/Wind turbine) power system is most suitable and cost competitive for the mentioned region.
